Show HN: Memory plugin for coding agents that remembers your coding&chat history

DeepMem launched a plugin for Claude Code and Cursor that provides persistent, semantically searchable memory across coding sessions, distributed through the Claude Code plugin marketplace and the Open Plugins manifest standard. The plugin exposes two MCP tools, deepmem_write for storing LLM-extracted conversation facts and deepmem_search for hybrid semantic search, and requires a DeepMem cloud API key prefixed dm_live_ obtained from deepmem.dev. Installation runs via the command /plugin marketplace add deepmemteam/deepmem-claude-plugin followed by /plugin install deepmem@deepmem, with source hosted at github.com/deepmemteam/deepmem.
